Following are <br />the reasons for requesting an extension. <br />Item 1: Submit[al of new map showing locations of stockpiled material <br />on the site. <br />EXTENSION REASON: The site has been flown and an Autocad digitized <br />map is being prepared by Analytical Surveys of Colorado Springs through <br />Leigh Whitehead and Associates. It is expected, according to Leigh <br />Whitehead and Associates, the map will be ready about the middle of <br />November. At that time we will have Leigh Whitehead and Associates <br />calculate the volumes of stockpiled material and those figures will be <br />submitted, along with a copy of the map showing the locations of the <br />stockpiles, by the end of November. <br />Item 2: Protection of soil stockpiles by seeding. <br />EXTENSION REASON; The original deadline in the inspection report <br />was October 29, 1991. For this site, seeding that early in the autumn <br />carries a considerable risk of failure. The probability of germination <br />and subsequent killing of the seedlings by a severe cold spell (like <br />what we are having right now) is too high. As a revegeta[ion specialist <br />I feel that any planting on this site should not occur earlier than the <br />last week or two of November. After then the soil is cold enough to <br />prevent significant germination and winter freeze thaw cycles help to <br />bury the seed to produce a rich growth the next spring. I would like to <br />request an extension until at least the end of November and i[ might be <br />better to delay it until the middle of December to be sure soil <br />
